rgeo-proj4

Gem Version Build Status

This project contains proj.4 extensions to the rgeo gem.

Documentation about proj.4 is available at http://proj4.org/.

Installation

Add this line to your Gemfile:

gem "rgeo-proj4"

And then execute:

$ bundle

Or install it yourself as:

$ gem install rgeo-proj4

Usage

Install proj.4 using your package manager:

Homebrew

brew install proj

Apt

apt-get install libproj-dev

Or download binaries at http://proj4.org/

By default, the gem looks for the Proj4 library in the following paths:

/usr/local
/usr/local/proj
/usr/local/proj4
/opt/local
/opt/proj
/opt/proj4
/opt
/usr
/Library/Frameworks/PROJ.framework/unix

If Proj4 is installed in a different location, you must provide its installation prefix directory using the --with-proj-dir option.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
